- Running out of space but love your location and neighbourhood?
- Need more room for your growing family without the stress of moving house?
- Want to add value to your property with a seamless, professional extension?
Creating home additions and extensions in Tauranga has become the smart choice for families who’ve outgrown their current space. Rather than dealing with the disruption and costs of relocating, homeowners across Te Puna, Mt Maunganui, and Papamoa are choosing to expand their existing homes. The challenge lies in finding builders who can deliver extensions that look like they’ve always been part of your house.
At Diack Homes, we specialise in creating extensions that enhance your lifestyle while protecting your investment. Our Licensed Building Practitioners understand Tauranga’s unique building environment—from coastal considerations to council requirements—ensuring your project meets all regulations while exceeding your expectations for quality and finish.

Expert Home Extensions Tauranga – Solving Space Problems Permanently
Space shortages don’t disappear on their own. Whether you need an extra bedroom for a new baby, a larger kitchen for family gatherings, or a home office for remote work, the right extension solves these problems permanently while adding significant value to your property.
Our recent projects demonstrate how thoughtful planning creates dramatic improvements. One family doubled their living space with an open-plan extension that flows seamlessly to their outdoor entertaining area. Another project added two bedrooms and a second bathroom, eliminating morning rush hour conflicts entirely.
Each home extension we complete undergoes rigorous quality control. We use construction methods proven to withstand Tauranga’s coastal climate, select materials that complement your existing home, and ensure every detail meets Master Build standards for lasting performance.
